Application Merch so, 1942, serial No. 26,815v 9 claims.v (ci. ail- 33)The present invention relates tota belt splice, and specifically to animprovement in splices generally of the character of the spliceldisclosed in my prior Patent 1,671,048. The primary object of thepresent invention is vto improve the said splice, in its constructionandffacility. of assembly, and to reducethe cost of such splice, both asto the production of itsparts. and *as to the labor involved inassembling it. Further objects of the invention will appear as. thedescription proceeds; f

To the accomplishment of the above and related objects, my invention maybe embodied in the form illustrated in the accompanying drawing,attentionbeing called to the fact, how-i ever, that the drawing isillustrative only, and that change may be made in the speciiioconstruction" illustrated and described, so long as l'the scope of theappended claims visnet violated. v

Figi ;1 is a side elevation 'of a fragment of a belt having its endsconnected by the splice' of the present invention; x f i Fig.A 2 is atransverse the direction of the arrows;

Fig, 3 is a longitudinal section taken substantially on the'line 3-3 ofFig. 2 and looking in the direction of the arrows; and 1 Fig. 4 is aplan View of one endoniy ef the section talien substan-V tially on theline 2 2 of Fig. 1 andlooking in' adjacent the' beit,- with' en undercutla. whichV projects beyond the extremity' I5 of the belt end` I3 and itsadapted to overlie the'belt end Ill. At

- its innermost extremity, `the undercut i8 `is A of transversely spacedlugs 23 blocksi I, andto the inner surface of which is 4 secured acorrespondingseries oftransversely rigid blocks I 2; The band I0transmits pulling force, while the blocks II and I2 give `transverserigidity tothe belt and, in the embodiment ofv the belt illustrated,constitute the friction ele` ments providing adriving connection betweendriving and driven V-type pulleys.. `rIhe splice Y'of thev presentinvention is intendedto :connect together the two end portions I3 and I4of the band I0. j, i

Desirably, the extremities I5 and/I6: of the respective beltend portionsI3 and `Illshould be brought as close as possible together by thesplice,

n so that said tWo extremities, lying V.substantially perpendicular tothe plane of the band body, shalllie Substantiallyin a Acommon planeperpendicular to the plane of such band body.' A block I'I, having itstransverseends shaped'g-to correspond to the transverse ends of theblocks I I, is secured to the outersurfacefof the belt end `portion I3..Said block is formed, in its'surface formed to provide a.part-cylindrical socket .l which is interrupted, at a plurality oftransversel-y spaced points, by lugs 2E forming aligned eyes 2l. Thecommon axisof said eyes 2l lies .substantially in theY plane of the'belt extremity l5, and Visspaced outwardly from the outer surface ofthe belt, inthe manner illustrated. f

Secured to the outer surface of the belt end I4 is a plate 22 formedtoprovide a plurality providing aligned eyes 2li. The common axis of saideyesZ/l lies substantially in the plane of the I I,-and is spacedkoutwardly fromface of the`.belt to an extent equal'to the spac ing o1"the axis ofthe eyes ZIifroin saidbelt sui-i face.Y

' f Itfollows from. the abovey description that',A

the lugs 23 will be yinterdigitated withthe lugs 2U to bring the eyes 24into registry with the eyes 2l; In this Aassembly step; the lugs '23will pass through the undercutV I 8 and snapinto the socket I9,saidsocket I9 being so shaped that the lugsv 23; cannot be removed therefromby relative movement parallel to the outer surface offthe belt body.VInstead, the block Il mustfbe moved upwardly and `tothe rightwith-respect to the platev 22, as viewed'in Fig. 3, to separate saidelements. In order to lock the block and'plate together, a pin 25 ispassed eyes 2| and 24. f i v y `.To the inner surface of the belt end i3is secured a' plate 22', similar in all respects to the plate 22, andformed to provide a transversely spaced series of lugs 23 formed toprovide aligned eyes 24. To the inner surface of the belt end I 4 issecured a block Il', similar in all respects totheblock I l. Said blockIl is formed with an yundercut I8', adapted to overlie the plate 22',

and formed at its inner edge'to provide parte., cylindrical socket ISinterrupted by atrans their interdigitated relation with the lugs 20`can` be elected only by movementfof the plate 22 belt extremity theouter sur` through the registering against the inner surface of theplate 22 and against a parallel surface of a slot 21 preferably out inthel block Il. .Thus the rivets 25,.p,assing,A

through the belt end I3 and engaging'the plate` 22' and the blockf H,secure said plate and said block to said belt end. Similarly, a seriesof transversely spaced rivets 28' passes through the plate 22, the beltend i4, and a portion ofv the.

block Il', being headed over against the outer surface of said plate 22and against a parallel surface formed in a preferably cutout slot 21' inthe block I'I to secure said plate 22 and block I1 to the belt end li.

It will be noted that the common axis ,of theV` 24 lies substantially inthe comeyes 2l and mon plane of the extremities l5 and Hina/nd'- spacedinwardly from the inner surfaceof the belt body by an amountsubstantially equal'. to the spacing of` the common axis of the eyes 2l"and` 24 outwardly from the outer surface ofthe.

belt body. The splice disclosed herein is made up, essentially, of sixpieces; viz., one piece'secured to each surface of each belt end, a pinfor connecting together the pieces securedto the outer surface of thebelt ends, and a pin ,for

securing together the pieces secured to theiinner surface of the beltends.
